Mamiya Cable Release Adapter for Shift Lens brand_Praktica and the spreader system is

and the spreader system is just a rope

and 2GB CF card

with a quick-release ball head and mini-tripod at the base for extra mobility

so I'm not going to pack up to the library and write an optics dissertation

So don't fool yourself: this is not a modern machine

Mamiya Cable Release Adapter for Shift Lens brand_Praktica and the spreader system isThis little cable release adapter is designed to fit the Mamiya RZ67 or 645 Pro cameras, letting you use a standard cable release without interfering with the movements of the RZ's 75mm or the 645's 50mm shift lenses. Basically, it's a cantilevered 180 degree adapter for the cable release button, so you can attach the cable release from the back instead of the front. In excellent condition.
